We demonstrate efficient compression of low-power 6 ps pulses down to 420 fs pedestal free pulses at 1.5 mum in an all-fiber scheme employing only 4 meters of As2Se3 fiber and a tailored chirped fiber Bragg grating.
All-fiber chirped-pulse amplification based on a large-mode-area Er:Yb-doped photonic-crystal fiber is presented. A dispersion-variable hybrid fiber stretcher compensates the peculiar dispersion of the hollow-core photonic-bandgap fiber compressor yielding transform-limited 440-fs pulses with 1-W average power.
We present a frequency comb-based, frequency-resolved coherent LIDAR (FReCL) that provides higher performance than that of conventional pulsed range/Doppler LIDARs, dramatically reduces local oscillator timing requirements, and compensates for path dispersion.
A new technique to control the chromatic dispersion of a uniform fiber Bragg grating based on the symmetrical bending for the tunable pulse repetition-rate multiplication is proposed and experimentally demonstrated.
Parabolic pulses from a similariton amplifier at 1550 nm are compressed using optimized linear compression in photonic bandgap fiber and soliton effect compression in dispersion-flattened highly nonlinear fiber. Transform-limited 20 fs pulses are obtained.
